Texture development and texture influence on the mechanical properties of the Mg-alloy AZ31

The texture influence on tensile tests of AZ31, one of the common Mg alloys, has been studied. Starting material was a rectangular extruded bar, which has a strong texture. Due to the preparation of three tensile samples with 0degrees, 45degrees, 90degrees to the extrusion direction, the initial bar texture influences differently on the mechanical behaviour under tensile load. This results in a variation of the yield strength (90 MPa and 175 MPa) the ultimate tensile strength (250 Mpa - 278 MPa) and the final texture. Experimental texture analysis was completed by texture simulations using the VPSC-model (Visco Plastic Self-Consistent). The good agreement between experimental and simulated pole figures allows the determination of the activated deformation modes related to the initial texture.
